SPINNING-MACHINE.

PatentedlDec.22,191d.

\ Application fiIed July 1, 1914. Serial No. 848,407.

To all whom it may concern:

Be it known that I, WILLIAM VVALLAon CALDWELL, a citizen of the United States, residing at Fall River, Bristol county, State of Massachusetts, have invented certain new and usefullmprovements in Spinning-Machines, of which the following is a full, clear, and exact description.

This invention relates to spinning machinery and is particularly applicable to twisting frames and the like employing wet twisting.

The present invention aims to improve the wetting action and is described in detail in the following specification taken in connection with the accompanying drawing illustrating my improvement and forming part of the specification.

In these drawings Figure 1 is a vertical sectional view through a frame embodying my improved construction, parts being shown inelevation and diagrammatically.

Fig. 2 is a fragmentary perspective view of the trough or receiver for the excess liquid extracted from the thread. Fig. 3 is a de-.

tail perspective view of a combined checking and guiding block cooperating with the trough to conduct the excess liquid thereto.

In the preferable form, I place the feed rolls on the dry side of the'wetting trough and provide a receptacle in addition to the wetting trough for the excess water, together with means for extracting the excess water and conducting it to this receptacle, and also means for guiding the thread as it comes from the wetting trough. I In the drawings 1 designates supporting means for a plurality of spools 2, from which the thread is drawn through suitably supported eyes 3, and is passed under a lower feed roller 4 and up and around an upper feed roller 5, both of these feed rollers being supported by'and journaled in a suitable support 6. Suitably supported on the frame forwardly of the feed rolls. 1 -5, is a wetting trough 7, preferably having a removable lining. Mounted within the trough at the edge adjacent the feed rolls and extending longitudinally of the trough, is fa' guide 8 preferably in the form of a-rod of glass or porcelain. This guide rod iswithin and below the trough with its under face below the normal water level therein. A supporting bracket positioned outside of the trough 7 is provided, a convenient method being to extend the far edge of the trough 7 toform a support and to mount on this sup port a bracket 9. Other supporting means form preferably of a metal trough 10 extending substantially the length of the wetting trough 7 and of the guide -8, this receptacle preferably having its ends closed by shallow walls 10 and being provided wlth a liquid discharge means such as the .tube 11. The sides of the trough are longitudinally corrugated to form guiding tongues 12, The trough being of metal, affords a sllght spring action at its upper ends where these tongues are located, so that the thread guiding blocks 13 may be held between the sides of the trough. In order to effectively do this, these blocks adjacent their bases are provided with grooves 14 therein complemental to the tongues 12, the thickness of the blocks being such that they may be. forced longitudinally of the trough, the tongues 12 thereof having a friction tight engagement in the grooves 14 of the blocks. These blocks are preferably formed of porcelain, although othermaterials may be used, and have their inner faces rounded in the direction of the guide 8, and provided with thread guiding grooves 15 therein. Each of the blocks is provided with a vertical bore 16 therethrough, which, at the upper end of the blockis counter-sunk, its

l block could be provided having the requisite number of guiding grooves'and bores 16. The threads passing'under the roller 8 will be drawn over and through the grooves 15 of the blocks, and thence downwardly and I preferably. through an eye 17 to aspinning ring or a twister 18 conventionally shown.

A better twisting action may be had if the threads are free as possible from any substance which would tend to make them stiff productive of numerous render the liquid more or less thick or mu-.

cilaginous, which is detrimental. By placing the part or parts 13 outside of or away from the wetting trough and by conducting the excess expressed liquid away from this wetting trough, such action is prevented. It is preferable to maintain a substantially normal liquid level within the wetting trough and any suitable means may be used.

In the drawings I show an overflow pipe 19, and a drip feed pipe 20, these parts being merely illustrative of one of many possible means of maintaining a normal liquid level.

The specific structure herein described is advantages as pointed out, but it will be obvious that this structure may be varied within the spirit of the invention and the scope of the appended claims.

What I claim, therefore, and desire to secure by Letters Patent is:

1. In a device of the character described, in combination, spool supporting means, a wetting trough, thread feed rollspositioned between said trough and said supporting means, a thread guide supported within said trough under which thread is designed to pass, thread guiding means positioned outside said trough to which thread passes from said trough guide, thread twisting means adjacent said uiding means to which the thread passes from said guiding means, an excess liquid receptacle separate from said wetting trough With means for conducting excess liquid from said guiding means to said receptacle.

2. In a device of the character described, in combination, spool supporting means, a trough for liquid, thread feed rolls positioned between said trough and said supporting means, a thread guide supported within said trough under which thread is designed to pass, supporting means positioned outside of and above said trough, an excess liquid receptacle separate from said wetting trough and mounted upon said sup porting means, thread guiding means carried by said receptacle and positioned outside of and above said trough and to which the thread passes from said trough guide, thread twisting means adjacent said guiding means to which the thread passes from said guiding means, and means for conducting excess liquid from said guiding means to said receptacle.

3. In a device of the character described, in combination, spool supporting means, a wetting trough, thread feed rolls positioned between .said trough and said supporting means, a thread guide supported within said trough under which thread is designed to pass, an excess liquid receptacle positioned above and outside of said wetting trough and a guiding member carried at the top of said receptacle having at least one guiding groove therein through which thread passes from said trough guide, said member also having an excess liquid conducting bore therein communicating with said groove and with said receptacle, and thread twisting means adjacent said guiding member to which thread passes from said guiding groove.

4. In a device of the character described, in combination, spool supporting means, a wetting trough, thread feed rolls positioned between said trough and said supporting means, means supported within said trough under which thread is designed to pass, a metal trough having an open top constructed and supported to extend longitudinally of said wetting trough and above and outside of the same, a block removably held between the walls of said metal trough and above and outside of said wetting trough, said block having at least one thread guiding groove therein to which thread passes from said wetting trough and having a bore therethrough communicating with said groove and with the interior of said metal trough, and thread twisting means to which thread passesfrom said groove.
